Specification of Letters Patent.

Application filed February 21, 1916.. Serial N 0. 79,586.

To all whom it may concern:

Be it known that we, FRANKLIN L. BAR- BER and EDWIN W. VVEBB, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Side Bearings for Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved side bearing for railway cars; and, to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several Views.

Referring to the drawings,

Figure 1 is a view, partly in plan and partly in horizontal section, of the improved side bearing, some parts being removed;

Fig. 2 is a view, partly in side elevation and partly in vertical section, some parts being removed; I

Fig. 3 is a view,partly in end elevation and partly in vertical section, taken on the line m m of Fig. 2;

Fig. 4: is an edge elevation of the improved key;

Fig. 5 is an end elevation of the same; and

Fig. 6 is a detail view in section taken on the line as w of Fig. 4. I

The numeral 1 indicates a cast metal housing provided with suitable reinforcing ribs and having integrally formed therewith a flanged base adapted to be riveted, bolted, or otherwise rigidly secured to the ends of a truck bolster. In the side walls of the housing, are formed bearing hubs 2 in which are mounted the ends of a pair of horizontally spaced heavy pins 3. On the intermediate portion of each pin 3, is loosely journaled a roller 4. The upper surfaces of these rollers 4 are located at the same altitude and extend above the upper top surface of the housing. The base of the housing, just below each roller 4, is cut away so that sand and dirt may work downward out of the housing, it being assumed, of course, that the truck bolster would have some provision, such as a passage, to permit the precipitation of the sand and dirt.

The bearing hubs 2 hold the pins 3 against lateral displacement, but are open at their ends to permit endwise displacement thereof. Bevel stop lugs 5 are integrally formed with one of the side walls of the housing and project upward, one into each of the bearing hubs 2, on the respective side of the housing. One end of each pin 3 is beveled at 6 and these beveled surfaces engage the stop lugs 5, prevent endwise displacement of the pins 3 through the respective side wall of the housing and also hold said pins against rotation.

To hold the pins 3 against endwise dis placement, away from the stop lugs 5, we provide for each of said pins an L-shape key 7, the body of which is segmental in cross section. The body of each key 7 is mounted in a correspondingly formed key seat 8. These key seats 8 are formed, one in the internal wall of each bearing hub 2 and extend completely therethrough. The inner ends of the key seats 8 extend into recesses 9 formed in the respective side wall of the housing and which recesses form lateral extensions of the key seat 8 to receive the short ends of the key 7 and hold the same against outward endwise displacement. The pins 3 hold the keys 7 against lateral displacement and it will be noted that the outer faces of the keys 7 have the same curvature as the internal walls of the bearing hubs 2 to receive the pins 3.

In assembling the improved side bearing, the keys 7 are first placed in the key seats 8 with their short ends extending into the recesses 9. The pins 3 are next inserted into the bearing hubs 2 in which the key seats 8 are formed and thereby hold the keys 7 against lateral displacement. The rollers 4: are then held within the housing 4, one in axial alinement with each pin 3. Said pins 3 are then moved endwise through the rollers 4L and into the other bearing hubs 2 with their bevel surfaces 6 in engagement with the stop lugs 5. The outer projecting ends of the keys 7 are then upset over the adjacent ends of the pins 3, which hold the same against endwise displacement, away from the stop lugs 5.
